MailDeck Reviews & Product Details

Buying solid inboxes for cold email and getting them set up to send is really straightforward here. It shows me the sending math and recommends which email provider - smtp, outlook or google - to use based on who I’m emailing, so I didn’t have to guess which pricing plan made the most sense. I connected my domains and my sequencer, and within a couple of hours the inboxes were loaded and ready to go. Overall, I was really happy with how easy the whole process was.

I’ve been using the inboxes for less than a month, and so far my emails have been landing outside of spam. Everything is working the way it should. Review collected by and hosted on G2.com.

We send a lot of cold email, and for a long time we didn’t have access to solid email verification. Our campaigns were stuck at a 5–7% bounce rate, which put strain on our in-house infrastructure and kept reply rates low. MailDeck provided pre-warmed inboxes at a price far below what it would have cost us to build and warm our own infrastructure from scratch. Review collected by and hosted on G2.com.

I'd like to see more integrations with sequencers. Our original sending tool didn't support auto-import, so getting inboxes into it took manual work. We later moved to PlusVibe, where the MailDeck team can import inboxes automatically right after an order, but that was more luck than planning on our side. Review collected by and hosted on G2.com.

The costs. We were paying one of the big-name inbox providers about 2.5x what MailDeck charges for mailboxes that perform exactly the same. We switched, kept the same budget, and went from 150-200k emails a month to 250-350k with no drop in inbox placement. Pre-warmed inboxes mean a new batch is sending at full speed the day it arrives instead of 14-18 days later. Review collected by and hosted on G2.com.

Hard to find much. If I'm picky I'd like an API or bulk export for mailbox credentials so we could plug new inboxes into our sequencer without any manual step at all. Right now their team handles the uploads for us, so it's not a real problem, just something I'd like to see eventually. Review collected by and hosted on G2.com.

Deliverability, honestly. We built our outbound on LinkedIn and only added email this quarter, and I can't afford to be the small company that lands in spam. With MailDeck's Google inboxes basically every email reaches the inbox and our reply rate has been around 1% from day one. The dashboard is simple, I can see every mailbox and its status at a glance, and connecting the inboxes to our sending tool took a few minutes. Review collected by and hosted on G2.com.

Not much yet. I've only used the Google inboxes so far, so I can't speak to the Outlook side. Review collected by and hosted on G2.com.

I connected it to our CRM through Zapier without much trouble, and that mattered more to me than anything else because our stack is basically held together with tape. The dashboard is pretty plain, and I wish I could sort mailboxes by campaign, but functionally everything I need is there. The price got us in the door, and the deliverability is what’s kept us.

the dashboard logs me out more often than it needs to. Review collected by and hosted on G2.com.

The setup process was incredibly easy. I opted for the diversified plan, because it’s cost-effective while also making it simple to get a reliable system in place with all three main email types. This was my first time setting up email infrastructure, so I really appreciated how they walked me through it. They sent me a Slack huddle and gave me updates at each step of the setup process. 99% of it was done for me. I can’t express how amazing that level of communication was, or how much confidence it gave me throughout. Review collected by and hosted on G2.com.

Their UI isn't the most refined, but at the end of the day, you aren't logging into their system outside of the setup. Review collected by and hosted on G2.com.

Their customer support was top notch. Even though they did take more time than the estimated time frame to get everything set up, communication from their team was overall decent. I think I am getting my money's worth, its definitely a little more expensive than other providers. Review collected by and hosted on G2.com.

The only bad experience with them was that they told me it was gonna take 2 days, but ended up taking 4 days. Review collected by and hosted on G2.com.

Warming up our Outlook Premium tenants took five days, which was a pleasant surprise because I expected it to take weeks. We chose them mainly for the US IPs, and they delivered exactly what we needed. Support also deserves a mention. After the switch, our spam rate was high and we couldn’t figure out why. They explained that Outlook scans messages before delivery and was flagging ours because of the links and open pixels. Review collected by and hosted on G2.com.

Everything has been good so far, and I’ll check back in soon with an update. Review collected by and hosted on G2.com.

The biggest upside is that MailDeck covers Microsoft 365 Outlook, Google Workspace, and Private SMTP under one provider. We started on Outlook tenants and later moved to the Diversified Stack, which let us match inbox type to audience segment without switching vendors. Inbox placement stays between 90-97% at 500K+ sends per month. Review collected by and hosted on G2.com.

Nothing. It's a well-made product that fits our needs completely Review collected by and hosted on G2.com.

My experience with maildeck has been amazing. The support is good, they reply quick and handle everything on time. I would recommend them. I have found that compared to others their pricing is good as well. Shout out to Yen, who has been very helpful. The process of getting the whole infrastructure sorted was quick and thorough as well.
